TO (AN whom it rimgl concern:

Be it known that I, Fnannnso (hcnnrinn, engineer, a subject of the King of Prussia, residing in the city of Yolklin on-tlie Saar, Poststrasse +15, Germany, ha c invented a certain new and useful improvement in Reels for Strap-Iron and the like, of which the following description, in connection with the accompanying drawings, a specification. line characters on the drawings representing like parts in the specification j.

The present invention relates an automatic reel for band or strap iron. in the reels heretofore used in connection with rolling-mills it is necessary to first fix the strapiron in a somewhat complicated manner (iii the reel, whereupon the reel can be put in operation. in this any time is lost, and than lore it has not linen possible until nor; to wind up the strap-iron coming from the rolling-mill directly and without intermediate opmation, because the strap-iron. would get 'llzorei'ore the lengtli of the hand and the pro duction is restricted.

The essential feature of the reel aci'aording to the present invention lies in the fact that the reclnvhoel 1 is rendered ma etic on its cirvumrerencc. 'lherefore the front end of the strap-iron ted to the circumference of the rotating wheel 1 is attracted, and in this Way a winding up is made possible Without a stopping of the. reelheing required for the purpose of attacliiin; the end of the strap-iron.

l n the accompanying drawings, Figure 1 is a side elevation, and Fig. 2 a front elevation of the reel.

'l hc reel or Winding yvheel 1 is mounted upon the shaft 2, supported by bearings 33 and 4-. lfpon the shaft are further arranged fixed bolt-Wheel 5 and a loose boltwheel 6 for the purpose of enabling the coupling or uncoupling of the reel with a drivingshalt. (Not shown.) A brake or friction wheel 7 is also mounted upon the shaft 2 in order to enable the stopping of the reel as quickly as possible. For the purpose of sin'iplicity the friction-band with level is omitlcd'in the drawings. In front of the wh n] l a known device for feeding the strapiron. Fig. 2, and ronsisting of the rolls 5% and .1 is -.in;'ed. The roll 8 is driven hy the shaft 3 l means of gear-Wheels 10 and 51. The roll is pressed, by means of a spring,

' against the roll 8. The reel-wheel 1 is constructed as a unipolar magnet-Wheel with two arm systems 12 and 14. The rechwheel also comprises a series of adjustable supports for the material to he Wound on the wheel. As shown, the supports 13 are pivotally mounted on the arm system 14, and they are provided with means whereby their tree ends may be adjusted in a radial direction, so as to vary the circumference of a circle including the supports.

Around the nave 14 a coil 15 is laid, which receives an electric current from the sliprings 16 and 17, being suitably connected with said rings, as indicated in dotted lines in Fig. 1. By this means the two arm systems 12 and 1 1 become magnetic in an opposite sense, so that the reel-Wheel on its circumference shows alternate y north and south poles n s n s. The shaft 2 is bored through. Through this boring a rod 18 is led, which carries at the belt-Wheel side threads 19, with a hand-wheel 20, by means of which the rod ":8 can he moved in axial direction. At the reelavheel side the rod 18 carries, a disk 21, with pivots 22. The supports 13 have pivots and 24. The pivots 22 and 23 are connected by links 25 of non-magnetic material. it by means of the hand-Wheel 20 the rod 18 is moved in the direction a I), the supports 13 are rocked around the pivots 24, whereby the radial distance of the supports- 13 from the shaft is varied, as indicated at 26, Where the strap-iron is coiled. In the position shownin Fig. 1 the supports 13 are adjusted at a radial distance somewhat greater than that of the ends of the arms 12.

The strap-iron is Wound up in Warm condition and will, owing to its beginning to cool off, contract close to the support 13 of the reel-Wheel. By means of the hand-wheel 20 the bundle of the strap-iron may be loosened. 27 is a ring of non-magnetic material with radial slots, Which serve as guides for the movable parts of the supports 13.

By means of pipe 28 coolingwvater can be supplied for cooling the coil 15.

'29 is an interposed heat-proof medium.

The strap-iron delivered by the finishingrolls 30 and 31 is brought into the rolls 8 and 9 by means of a box-shaped feeding-groove 32 with two high side Walls. The strap-iron engaged by the rolls 8 and 9 and is, by means of the curved piece 33, led to the circumference of the rotating reel-wheel 1. Owing to the magnetism of the arms, the

front-end of the strap-iron is attracted and held fast, and in this manner the'winding up isautomatlcally efleoted. When the entire band is wound u p, the reel is uncoupled. and i Patent, is

1. In a reel for band or strap iron and the like, the combination with the windh1gwheel, of means for magnetizing the Wheel whereby when the Wheel is ma netized the band is attracted and held while eing Wound upon the wheel, substantially described.

2. in a machine of the (diameter described, a winding-wheel comprising two arm systems, and means for magnetizing the arm systems, the arms of said systems being arranged alternately and oppositely magnetized, substantially as described.

3. in a niachineof the character described, a winding-wheel comprising two arm systems, adjustable supports mounted on the Wheel, and means for magnetizing the Wheel, the arms of said systems being arran ed alternatel and oppositely magnetize substantial y as described.

4. In a machine of the character described,

the combination with a shaft, of a Winding- Wheel of magnetic material mounted on the shaft, means for magnetizing the Wheel series of adjustable supports mounted. on the wheel, and means for adjustin the radial distance of the supports with re ation to the shaft to permit the material wound thereon to be removed, substantially as described.

, 5.111 a machine of the character described,

the combination with a hollow shaft, of a winding-wheel mounted thereon comprising two oppositely-magnetized arm systems, the

.arms of said systems being alternately arranged, a series of supports mounted on one f the arm systems, a rod extending through the shaft, connections between the rod and adjustable su ports, and means for adjusting the rod in t e shaft, substantially as described.

In witness whereof I have hereunto sir .ied my name in the presence of two subscribing witnesses.
